Django by default provides an authentication system configuration. User objects are the core of the authentication system.today we will implement Django’s authentication system.

Modules required :

django : django install

crispy_forms :

pip install --upgrade django-crispy-forms

Basic setup :

Start a project by the following command –

 django-admin startproject project

Change directory too project –

 cd project

Start the server- Start the server by typing following command in terminal –

 python manage.py runserver

To check whether the server is running or not go to a web browser and enter http://127.0.0.1:8000/ as URL.

Now stop the server by pressing

ctrl-c

Let’s create an app now called the “user”.

python manage.py startapp user

Goto user/ folder by doing: cd user and create a folder templates with files index.html, login.html, Email.html, register.html files.

Open the project folder using a text editor. The directory structure should look like this :

Now add the “user” app and “crispty_form” in your todo_site in settings.py,
and add

CRISPY_TEMPLATE_PACK = 'bootstrap3'

at last of settings.py

configure email settings in setting.py:

place your email and password here.

Edit urls.py file in project :

from django.contrib import admin 
from django.urls import path, include 
from user import views as user_view 
from django.contrib.auth import views as auth 
  
urlpatterns = [ 
  
    path('admin/', admin.site.urls), 
  
    ##### user related path##########################  
    path('', include('user.urls')), 
    path('login/', user_view.Login, name ='login'), 
    path('logout/', auth.LogoutView.as_view(template_name ='user / index.html'), name ='logout'), 
    path('register/', user_view.register, name ='register'), 
  
] 

Edit urls.py in user :

from django.urls import path, include 
from django.conf import settings 
from . import views 
from django.conf.urls.static import static 
  
urlpatterns = [ 
         path('', views.index, name ='index'), 
] 

Edit views.py in user :

from django.shortcuts import render, redirect 
from django.contrib import messages 
from django.contrib.auth import authenticate, login 
from django.contrib.auth.decorators import login_required 
from django.contrib.auth.forms import AuthenticationForm 
from .forms import UserRegisterForm 
from django.core.mail import send_mail 
from django.core.mail import EmailMultiAlternatives 
from django.template.loader import get_template 
from django.template import Context 
   
   
#################### index#######################################  
def index(request): 
    return render(request, 'user / index.html', {'title':'index'}) 
   
########### register here #####################################  
def register(request): 
    if request.method == 'POST': 
        form = UserRegisterForm(request.POST) 
        if form.is_valid(): 
            form.save() 
            username = form.cleaned_data.get('username') 
            email = form.cleaned_data.get('email') 
            ######################### mail system ####################################  
            htmly = get_template('user / Email.html') 
            d = { 'username': username } 
            subject, from_email, to = 'welcome', 'your_email@gmail.com', email 
            html_content = htmly.render(d) 
            msg = EmailMultiAlternatives(subject, html_content, from_email, [to]) 
            msg.attach_alternative(html_content, "text / html") 
            msg.send() 
            ##################################################################  
            messages.success(request, f'Your account has been created ! You are now able to log in') 
            return redirect('login') 
    else: 
        form = UserRegisterForm() 
    return render(request, 'user / register.html', {'form': form, 'title':'reqister here'}) 
   
################ login forms###################################################  
def Login(request): 
    if request.method == 'POST': 
   
        # AuthenticationForm_can_also_be_used__ 
   
        username = request.POST['username'] 
        password = request.POST['password'] 
        user = authenticate(request, username = username, password = password) 
        if user is not None: 
            form = login(request, user) 
            messages.success(request, f' wecome {username} !!') 
            return redirect('index') 
        else: 
            messages.info(request, f'account done not exit plz sign in') 
    form = AuthenticationForm() 
    return render(request, 'user / login.html', {'form':form, 'title':'log in'}) 

Configure your email here.

Now create a forms.py in user :

from django import forms 
from django.contrib.auth.models import User 
from django.contrib.auth.forms import UserCreationForm 
  
  
  
class UserRegisterForm(UserCreationForm): 
    email = forms.EmailField() 
    phone_no = forms.CharField(max_length = 20) 
    first_name = forms.CharField(max_length = 20) 
    last_name = forms.CharField(max_length = 20) 
    class Meta: 
        model = User 
        fields = ['username', 'email', 'phone_no', 'password1', 'password2'] 

Navigate to templates/user/ and edit files :

Make migrations and migrate it.

python manage.py makemigrations
python manage.py migrate

Now you can run the server to see your app.

python manage.py runserver
